Hi you could be having a. Problems in the JMeter java VM b. Problems in your test itself (like a synchronizing timer or a throughput controller) - This is something you have probably eliminated ? c. Problems in the system being tested (i.e. JMeter is generating the load , but your system under test paused so Jmeter isnt doing anything other than waiting) - Sounds like you have eliminated this possibility
For a) you probably have no way out of looking at the java VM when it is paused (take a thread dump - or hook up something like jconsole or run a profiler - look at GC running , memory usage etc) and then take it from there. Since you mentioned you are using Jmeter distributed mode , try eliminating that first - i.e. running a single machine test (perhaps with half the load) and seeing whether you see same behavior or not - if you do then you can probably take a thread dump (ctrl+break or kill -3 and see what JMeter is doing at that time - you can also enable GC logs to see what the memory usage looks and whether GC is running or not).
